c++ - 初始目录不适用于 CFileDialog

Question

我正在使用 CFileDialog，我设置了如下所示的初始路径，如代码所示。它不工作。如果我犯了错误，请纠正我。

   CFileDialog* filedlg = new CFileDialog(TRUE,(LPCTSTR)NULL ,  (LPCTSTR)NULL , OFN_HIDEREADONLY| OFN_ENABLESIZING , (LPCTSTR)NULL , FromHandle (hImgDlg) ,0 , FALSE  );

   filedlg ->m_ofn.lpstrInitialDir = "C:\\" ;

   if ( filedlg ->DoModal() == IDOK )
   {
       /***  do somthing here *****/
   }

Answer 1

如果您看到 OPENFILENAME 的引用结构，您将看到对于 lpstrInitialDir 字段，它指出:

If lpstrInitialDir has the same value as was passed the first time the application used an Open or Save As dialog box, the path most recently selected by the user is used as the initial directory.

这意味着 lpstrInitialDir 字段实际上只能在您第一次在程序中使用该对话框时使用。其余时间它将使用用户选择的最后一个目录。
